“An earthquake with a preliminary magnitude of 5.0 struck the northern part of Nagano prefecture in central Japan on Saturday, the country’s weather agency said.”
SINGLE SOURCE
The claim specifies a preliminary magnitude 5.0 earthquake in northern Nagano on Saturday. One web search result reports a magnitude 5.0 earthquake in northern Nagano Prefecture on April 18, but other web results mention different magnitudes (5.5) or locations (Tokyo). Since only one source directly matches the specific details (Mag 5.0, Northern Nagano, Saturday), it cannot be corroborated.
